Steam turbines from 10 kW to 1,900 MW

With over a century of experience and continuous development in our steam turbine technology, Siemens is a prime partner for your business.

More than 120,000 steam turbines delivered worldwide prove that we are a reliable and experienced partner. Our steam turbines work as generator drives or as mechanical drives for compressors or pumps. They play a significant role in many combined cycle and cogeneration plants and in industrial applications.

Also in the renewable energy sector steam turbines are often applied. Whether power generation plants, or district heating, biomass, waste-to-energy, seawater desalination, or solar heat: There is a wide range of applications for steam turbines made by Siemens.

Steam from renewable sources

Providing a future-proof source of electricity and contributing to lower CO₂ emissions, power produced from biomass or solarthermal heat is increasingly economically viable. Hundreds of Siemens steam turbines powered by steam from renewable fuel have been installed worldwide.

Proven utility steam turbines

Siemens offers a comprehensive range of steam turbine products in the power output range from 90 to 1,900 MW. These are used in conventional fossil-fired steam power plants as well as in nuclear and combined cycle power plants. With more than 8,000 steam turbines in service worldwide we provide proven technology, adapted to the specific local conditions.

Tailor-made and flexible: our industrial steam turbines

As a market leader for industrial steam turbines, we offer a comprehensive range of reliable and versatile steam turbines for the power output range from 2 to 250 MW. Our industrial steam turbines are designed for easy constructability, fast start-up and economical operation.

After 62 years of continuous operation, the Oxea GmbH in Oberhausen/Germany decided to replace the Siemens steam turbine against an SST-600. Although the historical steam turbine was still working fine, increasing the overall efficiency of the power plant gave the necessary impulse for the replacement. The result: higher profitability and a 15 percent higher efficiency of the energy cycle. The new steam turbine is much smaller in size and demands 114 tons of steam per hour compared to the 130 tons before modernization. Also the leakage steam could be reduced from 1000 kg to only 100 kg.

The heart of every power plant

Siemens Steam Turbines are an essential piece of turbomachinery to many power plants worldwide. They are applied either as a generator drive or a mechanical drive for pumps and compressors. The modular design concept of all steam turbines ensures high flexibility, availability and a reduction of time-to-market.

Our scope of supply

Our steam turbines are designed after a standardized modularized system to design customized steam turbines. This allows highest flexibility in manufacturing and ensures reliability and availability of our products. After extensive consultancy and analysis of your water-steam cycle, we deliver tailor-made steam turbines which fit exactly to your needs.

Continuous technological development

Enhanced steam turbine design

With the Enhanced Platform concept Siemens finalized former company associations by combining all well proven technical features from the several product lines in one common basis. The Enhanced Platform concept follows a modularized system to create customized steam turbine solutions.

Supercritical Steam

Efforts to reduce CO₂ emissions undertaken in the past have focused on large, state-of-the-art steam power plants in the higher output classes. Going forward, the good experiences gained from existing high‑end ultra‑super critical (USC) coal-fired power plants needs to be transferred to power plants of the 350-MW size.

Oberhausen, Germany (2017)

The chemical production complex of the company Oxea GmbH, operates around the clock, 365 days a year. The company now installed a modern, high-efficiency turbine-generator unit to replace an historical 63-year-old radial steam turbine from Siemens that has clocked 400,000 operating hours.

The new turboset enhances cost-effectiveness and thus profitability, while increasing energy-cycle efficiency by 15 percent.

11 steam turbines are leaving to Bolivia

Siemens is helping to expand three Bolivian combined cycle power plants. This project will add more than one gigawatt to the local power grid, increasing the installed power generating capacity by 66 percent. This will provide a reliable energy supply for the country's population and lay the groundwork for future exports.
